Introduction
Childhood and adolescence correspond to critical phases of physical growth, brain maturation, and emotional development; therefore, glycemic fluctuations impact proper development. The use of Continuous Glucose Monitoring (CGM) in patients in this age group with Type 1 Diabetes Mellitus (DM1) represents an advancement in clinical care and quality of life. Providing access to this technology in the public health system may promote equity and improve metabolic control.
Objectives
To evaluate the clinical effectiveness of CGM use in children and adolescents with DM1 followed in a specialized outpatient clinic.
Methods
An observational, quantitative, cross-sectional study, based on medical records of 189 patients, of whom 29 were excluded due to missing HbA1c data, 106 using self-monitoring of blood glucose (SMBG) and 54 using CGM, aged 2 to 18 years, followed accompanied by a multidisciplinary care at the Specialized Center for Diabetes, Obesity, and Hypertension of the Federal District, Brazil. Statistical analysis was performed using Student’s t-test. Approved by the Ethics Committee (No. 95934426.2.0000.5553).
Results
The mean age of the participants was 11.8 years, with mean duration of diabetes of 4.7 years. The CGM group had an average HbA1c of 7.4%, while the group that used a glucometer had an average of 9.2%, with a statistically significant difference between the groups (p < 0.001).
Conclusions
Despite the socioeconomic limitations faced by patients in the public health service that hinder the adequate management of type 1 diabetes (T1D), the use of CGM was associated with better glycemic control compared to the use of a conventional glucometer. These findings suggest that expanding access to CGM may significantly improve care and reducing the risk of long-term complications in this population, particularly when combined with multidisciplinary care.
